I would have liked to see some home servers, xbox 360s and Microsoft Surfaces.
It's almost guaranteed that when Apple come up with something their competitors end up doing the same. It makes them look daft and devoid of ideas.
Example: Apple make Macbooks and iMacs white. About 4 years later I start seeing white consumer electronics everywhere, around this time Apple release the first unibody Macbooks which are silver and black. Now all of a sudden the white imitation stuff just looks dated. Basically Apple are running rings around their competitors and I for one find it pretty damn funny.
Looking forward to seeing a Microsoft store in Indianapolis... Then again I'm moving...
